There were 176 plots (88 plots per replication) in this field. The
plots were four-row plots. 
The plot numbers shown in the image correspond to those included in the QR codes.
North Platte
Only the Hybrid HIPS population was grown at this location. Plot numbers are unique across the North Platte location, but range and row numbers were duplicated in each field. Each field is a different irrigation treatment. To account for this, the location was split in 3 by irrigation treatment in the data. North Platte1 is the full irrigation field; North Platte2 is the partial irrigation field, and North Platte3 is the dryland, i.e. rainfed, field. The plots were 4-row, 20 foot plots, with 17 feet of the plot planted and 3 feet of alley. Nitrogen treatments were blocked within each irrigation treatment. The full irrigation field was planted on May 17, 2022, and harvested on October 21, 2022 and November 1, 2022 with planted plot lengths of 17.5 feet. The partial irrigation field was planted on May 17, 2022 and harvested October 26 - 28, 2022 with planted plot lengths of 17.5 feet. The dryland field was planted on May 18, 2022 and harvested on October 19-21 and 24, 2022 with planted plot lengths of 17 feet.
In the image above, the blue rectangle is the approximate location of the full irrigation field, the yellow rectangle is the approximate location of the partial irrigation field, and the red rectangle is the approximate location of the dryland field.
Scottsbluff
The field was irrigated for one hour from 4:00 p.m. to 5:00 p.m. every Friday evening. The row spacing was 30”. In-field measurements (flowering time, height data, and combine yield measurements) use the range-row system defined in the sheet ‘Layout (Original)’ of the files ‘Scottsbluff Hybrid HIPS - Summary.xlsx’ and ‘Scottsbluff Inbred HIPS - Summary.xlsx’. In the data, these range-row assignments were dropped in favor of using the range-row assignments listed in the QR codes and used by the ear phenotype and NIR grain composition measurements, which better capture the spatial distance between plots where there are border plots. The geographic location within the field of a plot by its plot number is the same in both layouts, but the range-row numbering is different. The range-row system used in the QR codes and the data is depicted in the sheet ‘Layout (Modified)’ of the files ‘Scottsbluff Hybrid HIPS - Summary’ and ‘Scottsbluff Inbred HIPS - Summary.xlsx’, and shown in the image below. ‘Fill’ is equivalent to ‘Border’ at other locations. The field was planted north to south and together, the inbred and hybrid fields are 625 feet north to south. The fields were planted on May 19, 2022. A combination of 10-34-0 (NPK) liquid fertilizer and urea were applied to meet the nitrogen treatment level requirements, as shown below.
Inbred HIPS field
The plots were 10 foot (7.5 feet planted), 2-row plots.
Hybrid HIPS field
Based on yield data and grain protein content, it was determined that the labels in the QR codes for the high and low nitrogen treatments were reversed. The QR codes in the data reflect the content of the original QR codes, and the nitrogen treatment variable reflects the actual level of nitrogen the plot received. The plots were 25 foot (22.5 feet planted), 4-row plots and the middle two rows were harvested.
## Crawfordsville These fields were planted on May 11, 2022 and
harvested on October 7, 2022. Both the inbred and hybrid fields had 3
nitrogen treatments (High, Medium, and Low). The field coordinates were
41.199066, -91.486991. The nitrogen treatments were applied on June 2,
2022 using 32% UAN.
Ames
These fields were planted on May 23, 2022 and harvested on October 16, 2022. Both the inbred and hybrid fields had 3 nitrogen treatments (High, Medium, and Low). The field coordinates were 42.012376, -93.737301. The nitrogen treatments were applied on May 21, 2022 using urea.
